Terry,
1) CP SET SRM commands require privclass 'A' (or a privclass for those
commands that you added another privclass via CP MODIFY COMMAND).
--->>Does AUTOLOG2 have that priv? <<---
2) Why not just have AUTOLOG1 or OPERATOR issue performance commands,
thereby letting your External Security Manager benefit from their
performance change? If OPERATOR does it, you may want to place those
"special commands" on OPERATOR 192 or some other disk that the OPERATOR
userid cannot LINK R/W.
3) Performance command changes before/after are good to see on the
OPERATOR console log. I placed all ours in a single command called
"PERFCMDS EXEC" (actually, "PERFCMDS VMOPER", since OPERATOR runs them
after VM:Operator has its own console log started). PERFCMDS provides
documentation on OPERATOR of what the setting was before, and of the
actual command.
Here's a cut/paste, modified (but not tested) to run on OPERATOR (change
as needed to run from elsewhere):
---<snip>---
/* PERFCMDS EXEC */
/* set recommended performance metrics for zLinux */
/* Call PerfCmd 'command , settings' */
/* (the 'command' part is used by CP QUERY and CP SET, 'settings'
only by CP SET) */
Call PerfCmd 'SRM STORBUF , 300 250 200'
Call PerfCmd 'SRM LDBUF , 100 100 100'
/* set Delay for Linux Guest Shutdown */
Call PerfCmd 'SIGNAL SHUTDOWN , 180' /* Allow Linux Guests 3 mins to
shutdown*/
Call PerfCmd 'MDC , STOR 0M 256M'
Call PerfCmd 'MDC , XSTOR 0M 0M' /* Will cause repeat QUERY MDC */
Exit rc
PerfCmd:
parse arg cmd ',' settings
parse var cmd w1 w2 w3 .
say 'CP QUERY' cmd /* Document "before" setting */
'CP QUERY' cmd
say 'CP SET ' cmd settings
'CP SET ' cmd settings
trace o
Return

AUTOLOG
Hi
I am setting some parameters in my AUTOLOG2 PROFILE EXEC, but they do not
seem to be taking affect. Is there something else I am missing?
The ?CP XAUTLOG xxxxxxx? seems to be working fine but commands such as the
following do not take affect:
/* set recommended performance metrics for zLinux */
'CP SET SRM STORBUF 300 250 200'
'CP SET LDBUF 100 100 100'
/* set Delay for Linux Guest Shutdown */
'CP SET SIGNAL SHUTDOWN 180' /* Allow Linux Guests 3 mins to shutdown*/
'CP SET MDC STOR 0M 256M'
'CP SET MDC XSTOR 0M 0M'
To test these I issue the xautolog autolog2 command from MAINT after I
have LINKED to AUTOLOG2.
Thank You,
Terry Martin
